Yes, that's a really good question. It must be able to inhibit other organisms ability to uptake calcium, in my case after a year my doser was dialed back from 72ml/d ca, 62ml/d alk and 30ml/d mag to 30ml/d ca, 20ml/d alk and 0 ml/d mag and my mag got over 1500ppm. Coraline algae was receding and turning white and the couple sps corals I have weren't growing much.
